UNITED STATES PATENT OFF-ICE.

ERNST SIMON, OF WERDEN-ON-THE-RUHR, GERMANY. V

Application filed March 7, 1924,'ser1a1 No. 697,510, and in GermanyMarch 10, 1 923.;

My invention relates to improvements in apparatus for chargingfirep'laces with highly inflammable loose fuel such assaw dust, woodshavings, and the like, and the object of the improvements is to providean apparatus by means of which the fuel is uniformly distributed on thegrate. Vith this object in view my invention consists in. supplying thefuel to the fire place through a passage divided into branches passingthrough the top wall of the fire place and equipping the said passage atthe point where it is divided into branches with a-distributing membersuch as a rockable gate supplying the fuel in regular succession to theindividual branches. In an apparatus of this type a light and easilymovable gate may be provided which can be operated by gravity of thefuel falling through the passage. I have found that when thus supplyingthe fuel a. uniform combustion is insured, the fuel being burnt whenfalling from the branch passages or being uniformly dis; trib-uted onthe grate.

For the purpose of explaining the invention one embodiment thereof isshown in the accompanying drawing by way of tion.

The drawing is a sectional elevation of a/ fire place and the fuelsupplying apparatus taken longitudinally through the fire place.

In the example shown in the drawing, a fire place Z) having a grate aand atop a, is provided with a fuel supply apparatus consisting of a.vertical pipe 7 which is divided into four branch passages 11, 12, 13and 14; passing through the top wall of the f re place, and providedwith a rockable gate 8. The gate 8 is made with two side walls forming adownwardly tapering passage and its inlet end is always in unreducedcommunication with the passage 7, and the area of its dischargecorresponds to the area 0 the branches 11, 12, 13 and 14.

The loose fuel such as wood shavings or saw dust is supplied to the pipe7 from a work shop, or other suitable source, by means of air draught orother means, and

it flows uniformly downwardly through the 'illustrapipe 7. According tothe position of the gate 8 the main part of thefuel is'directed througheither one of the passages 11, 12,

13 or 14 and discharged therefrom to the front part, the median part, orthe rear part of the grate a. As the fuel fall freely through the pipe 7it is uniformly dis tributed.

Any preferred means may be provided for imparting to and fro movement tothe gate.

valve structure above said top wall, said structure including a casingand a single distributing valve mounted for oscillation therein, thecasing having at the top a port of substantial area for admission offuel in communication with a fuel supply conduit,

and the casing also having at the bottom a series of adjacent distinctdistribution ports,

the valve being of tubular downwardly tapering interior form anddesigned to afford selective communication between said inlet port and asingle one of said distribution ports when selectively positioned,passages extending through said top wall on, lines radiatingsubstantially from the center of oscillation of said valve and enteringthe top of the fire box at spaced points and directed to afforddistribution of fuel over substantially the entire grate area, and meansexternal to said valve casing for selectively positioning the-valve thusto afford distribution of the fuel throughthe several passages over theentire grate.

In testimony whereof I hereunto afiix my signature.

ERNST SIMON.
